St. Petersburg, Florida -- A bar manager was arrested Monday after an confrontation with a patron at a bar left the man in a coma.

St. Pete Police say Jeremy Fisher was at Suite Six Club on Central Avenue around 2:30 a.m. Sunday, when he reportedly made a female bartender uncomfortable. Feeling threatened by Fisher, the bartender called over her manager, 24-year-old Blake Ambrester, to intervene.

Ambrester reportedly asked Fisher to leave, but he refused and became physically resistant. Police say Ambrester placed Fisher in a "choke hold" and dragged him outside. Investigators say it appears Fisher passed out as he was being dragged away and when Ambrester released him from his hold, Fisher fell face-first onto the sidewalk, injuring his head and neck.

When Ambrester realized Fisher was injured, he flagged down an officer for help.

Fisher, 39, is currently in a coma at Bayfront Medical Center. He also sustained fractures to his face and an injury to his neck that will require surgery.

After an investigation, Ambrester was arrested Monday and charged with aggravated battery, due to the severity of Fisher's injuries.

Ambrester has been arrested several times in the past on battery charges.
